Star EV Golf Cart Batteries & Lithium Conversion Kits

Lithium Rhino builds drop-in Icon golf cart batteries and lithium conversion kits for every Icon EV model, i20, i40, i40L, i60, i60L, i80, and the newer ICON X series. Each 48-volt LiFePO4 kit ships with an ultra-fast lithium charger, isolated 12V reducer, LCD touchscreen, mounting hardware, and lead-acid removal gear in one box. Whether you're replacing a worn lead-acid pack or upgrading from Icon's factory 51V/105Ah ECO Lithium for more range and a longer warranty, the Rhino kit installs in a single afternoon and is backed by an 8-year full-coverage warranty and 6,000+ charge cycles.

Why upgrade your Icon golf cart battery to Lithium Rhino?

Icon golf carts ship from the factory in one of two battery configurations: a lead-acid pack (typically six 8-volt flooded or AGM batteries) on older builds, or Icon's factory 51V/105Ah ECO Lithium pack on most 2023+ models. Both can be improved.

If your Icon still runs lead-acid, a Lithium Rhino kit eliminates 300+ lbs of dead weight, doubles drive range, cuts charge time in half, and lasts 10–12+ years instead of 3–5. If your Icon already has the factory ECO Lithium, a Rhino upgrade unlocks more capacity (up to 170Ah vs the factory 105Ah), higher continuous current with a 300A BMS for hills and accessories, and an 8-year full-coverage warranty versus the more limited factory coverage.

Either way, the end result is the same, an Icon that drives further, charges faster, and outlasts the cart itself.

Lithium Rhino Icon battery options by model

Every Icon model is built on a 48V platform, so all five kits in this collection are voltage-compatible across the entire i-series lineup. The choice comes down to capacity (Ah) and continuous current based on how you actually use the cart:

Icon i20 / i20U / i20UL (2-seater & utility)
The 2-seater i20 is light and efficient, the 48V 105Ah kit is the standard recommendation and gives 40–55 miles of range. Utility i20U and i20UL owners hauling cargo daily should consider the 48V 120Ah for extra capacity. The 48V 105Ah CUBE is the right pick if vertical space in the battery bay is limited.

Icon i40, i40L, i40F, i40-ECO (4-seater variants)
The i40 line is Icon's best-seller, 4-passenger seating, 5kW AC motor, 450A controller. For everyday neighborhood and golf use, the 48V 105Ah kit is the sweet spot. Lifted i40Ls and i40F flatbeds carrying weight on hills are better matched to the 48V 120Ah or 48V 170Ah 300A BMS kit. i40-ECO owners stepping up from the factory ECO Lithium will feel an immediate range jump with the 48V 120Ah.

Icon i60, i60L, i60F (6-seater variants)
Six-passenger Icons carry more weight, more often. The 48V 120Ah is the practical daily-driver upgrade, while the 48V 170Ah 300A BMS is the right call for resort fleets, hospitality use, and i60Ls running 23"+ tires.

Icon i80 (8-seater)
The i80 is Icon's largest passenger model, 14 feet long, 8 seats, designed for commercial transport. The 48V 170Ah 300A BMS kit is purpose-built for this kind of continuous, full-load use. Pair it with the included isolated 12V reducer to power onboard lighting, fans, and audio without draining the traction pack.

ICON X series and EPIC FX (newer 2025–2026 models)
The ICON X and EPIC FX share the same 48V architecture and battery bay layout as the i-series. The 48V 105Ah or 48V 120Ah kits are direct fits for these newer models. For cold-climate buyers (Northeast, Midwest, mountain states), the 48V 120Ah Self-Heated kit allows safe charging below freezing.

What is the best lithium battery for an Icon golf cart?

The honest answer depends on how you use the cart, but here's the short version most Icon owners land on:

• Light use, 2–4 seater, neighborhood + golf: 48V 105Ah Lithium Rhino Conversion Kit
• Daily driver, 4–6 seater, lifted or hilly terrain: 48V 120Ah Lithium Rhino Conversion Kit
• i80 / fleet / heavy commercial / "big lithium battery" buyers: 48V 170Ah 300A BMS Lithium Rhino Conversion Kit
• Cold-climate owners (charging below freezing): 48V 120Ah Self-Heated Lithium Rhino Kit
• Compact battery bay (space-constrained installs): 48V 105Ah CUBE Lithium Rhino Kit

Compared to Icon's factory 51V/105Ah ECO Lithium, every Lithium Rhino kit offers either more amp-hours, more continuous current, a longer warranty (8-year full coverage), or all three.

The biggest lithium battery for an Icon: 48V 170Ah 300A BMS

For Icon owners specifically searching for a big lithium battery for an Icon golf cart, the 48V 170Ah Lithium Rhino Conversion Kit with 300A BMS is the largest single-pack option in this collection. Highlights:

• 170 amp-hours: 70–90+ miles of real-world range per charge
• 300A continuous BMS: handles steep grades, heavy loads, and high-current accessories without throttling
• Drop-in for Icon i40L, i60, i60L, i80 battery bays
• 8-year full-coverage warranty with 6,000+ cycle life
• Same one-box install: no second pack, no series wiring

This is the kit for Icon owners running fleet operations, oversized tires, off-road tracks, or simply wanting the longest possible range from a single charge.

Icon lithium battery warranty

Lithium Rhino offers an 8-year full-coverage warranty on every Icon battery, significantly longer than typical factory and aftermarket lithium warranties. Full coverage means no proration, no fleet exclusions, and no charge-cycle cap inside the warranty window. For Icon owners comparing options: Icon's factory ECO Lithium typically carries a 2–5 year prorated warranty depending on the year and dealer.

Frequently Asked Questions

What battery does an Icon golf cart use?
All Icon golf carts run on a 48-volt battery system. Older Icons ship with six 8-volt flooded lead-acid or AGM batteries, while most 2023+ Icons ship with a factory 51V/105Ah ECO Lithium pack. Both setups can be upgraded to a single Lithium Rhino LiFePO4 conversion kit for more range, longer life, and an 8-year warranty.

Can I put a lithium battery in my Icon golf cart?
Yes. Every Lithium Rhino 48V kit is engineered as a direct drop-in replacement for Icon i20, i40, i60, i80, ICON X, and EPIC FX battery bays. The kit includes Icon-compatible charge port plug, mounting brackets, and the isolated 12V reducer needed to power factory accessories.

Is Lithium Rhino better than the Icon factory ECO Lithium battery?
For most Icon owners, yes. Rhino kits offer more amp-hour options (up to 170Ah vs the factory 105Ah), a longer 8-year full-coverage warranty versus the factory's typical 2–5 year prorated warranty, 6,000+ rated cycle life, and a 300A BMS option for heavy use. Factory ECO Lithium is fine for casual use; Rhino is the upgrade path when you want more range, more current, or longer coverage.

What is the best lithium battery for an Icon i40?
For most Icon i40 owners, the 48V 105Ah Lithium Rhino Conversion Kit is the best match, 40–55 miles per charge, drop-in fit, $2,299. If you run a lifted i40L, carry weight on hills, or want more range, step up to the 48V 120Ah kit.

What is the biggest lithium battery for an Icon golf cart?
The 48V 170Ah Lithium Rhino 300A BMS Conversion Kit is the largest single-pack option for Icon golf carts in this collection. It delivers 70–90+ miles of range and handles continuous high-current loads, ideal for Icon i80, i60L, fleet carts, and heavily accessorized builds.

How long do Icon lithium batteries last?
A Lithium Rhino LiFePO4 battery is rated for 6,000+ charge cycles, which translates to roughly 10–12+ years of typical Icon golf cart use. Factory ECO Lithium batteries are typically rated for 3,000–5,000 cycles. Lead-acid Icon batteries average 3–5 years before noticeable range loss.

How much does an Icon lithium battery conversion cost?
Lithium Rhino Icon conversion kits range from $2,299 (48V 105Ah and 48V 105Ah CUBE) to $3,499 (48V 170Ah 300A BMS). The mid-tier 48V 120Ah is $2,699. Financing is available from $36/month at 0% APR through Shop Pay, Affirm, and PayPal.

Will a lithium conversion void my Icon warranty?
A lithium conversion does not void Icon's chassis or drivetrain warranty in most cases, since the battery is an aftermarket upgrade. If your Icon currently runs the factory ECO Lithium, replacing it will end the battery-specific factory warranty — but the Lithium Rhino kit replaces it with its own 8-year full-coverage warranty. Check current Icon warranty terms for your specific model year.

How long does it take to install an Icon lithium battery kit?
Most Icon owners complete the install in 2–4 hours. The kit includes step-by-step instructions, all hardware, and free access to a 30-minute video install call with a USA-based Rhino tech.

Do I need a new charger for a lithium Icon battery?
Yes, lead-acid chargers will damage a lithium battery, and the factory ECO Lithium charger is not compatible with Rhino's BMS profile. Every Lithium Rhino Icon kit ships with the correct lithium charger and an Icon-compatible plug, so no separate purchase is required.

Can I charge my Icon lithium battery in cold weather?
Standard LiFePO4 batteries should not be charged below 32°F. For cold-climate Icon owners, the 48V 120Ah Self-Heated Lithium Rhino Kit includes an internal heating element that pre-warms the cells before charging, allowing safe operation down to –4°F.
